Fig. 1. Differences between vertical and horizontal markets in order to adopt a middleware for interactive applications in digital television. These ideas are shown in Fig. 1. In vertical markets, a single company integrates all the steps of the value chain and a proprietary middleware can be used. However, in a horizontal market, which is usually the case of digital terrestrial television (DTT), a standard middleware is needed to ensure the interoperability between steps in the value chain and to reduce the set-top box deployment costs [3].
